I'm currently watching an auction on EBAY for My Little Pony trade edition. The book is in clean condition but the slipcase is in less than desirable condition. I see on its page on this website that the slipcase is frequently in less than pristine condition. OK here's the question:

How much added value does the case add to a book? Obviously, a case is better than not having one. If a book was issued with a slipcase, how much of its overall value is in the case?

IMO. If the book was issued with a slipcase, then it is almost worthless without it. (Unless the book is signed by King.)
